    Nasa's Voyager 1 spacecraft now out of Solar System after 36 years of travel

    Advert.
    Scientists have been debating for more than a year whether Nasa's 36-year-old Voyager 1 spacecraft has left the solar system and become the first human-made object to reach interstellar space.

    By a fluke measurement, they now know definitively it has.

    "We made it," lead Voyager scientist Edward Stone, from the California Institute of Technology, told reporters on Thursday.

    The key piece of evidence came by chance when a pair of solar flares blasted charged particles in Voyager's direction in 2011 and 2012. It took a year for the particles to reach the spacecraft, providing information that could be used to determine how dense the plasma was in Voyager's location.

    Plasma consists of charged particles and is more prevalent in the extreme cold of interstellar space than in the hot bubble of solar wind that permeates the solar system.

    Do you know it is traveling at a speed of 16 lakh Km per day which roughly makes 66666 km PER hour and still it took it 36 years to cross the solar system.

    They even have lots of stuff from earth on it in case some other race ever finds it. (if ever).
